Thats it!

In HomeServlet.java, there's a missing semicolon in the static block.

Google AppEngine? complains that the openid-filter parameter <load-on-startup>1</load-on-startup> is misplaced in the web.xml file. It wants to see <init-param> instead. Any ideas where this should really go?

my project work on appengine 1.4.2 and 1.5.5, any other version not working. May be your problem in appengine version?
